The graph shows how many centimeters above a table top, y, a painted spot on an automated hamster wheel is for a given number of seconds x.

How many degrees is the painted spot turning in 0.75 s?

At   0 sec.....the painted spot is at its lowest point

 

The period (one complete revolution) is 1.5 sec....it turns through 360°  during this time....

 

So.....(1/2) of this = .75sec.....so.....it turns through 180°  in .75 sec

 

 

cool cool cool
